AngularJS filter search

Question

I have tried the filter logic from angular to one of the unordered list. But, the search filter is working after typed 3 characters of the name, sometimes giving wrong search results.

 <input type='text' ng-model='searchString' placeholder="Search a name..." />


<ul class="nav">
     <li class="active" ng-repeat="item in artists.People | filter :searchString">
           <a href ng-click='setSelectedArtist(item)'>{{item.name}}</a>
     </li>
 </ul>

JSON:

          ]
       }
    ]
 }

Here is the plnkr code.

Ex: Start typing 'si', you will end up with two results where first one(frank wang) is not correct.

And, this is the reference plnkr where I'm referring for.

Answer 1

You would need to specify which object property, in this case name for the filter to filter against:

<input type='text' ng-model='searchString' placeholder="Search a name..." />

<ul class="nav">
  <li class="active" ng-repeat="item in artists.People | filter: { name: searchString }">
    <a href ng-click='setSelectedArtist(item)'>{{item.name}}</a>
  </li>
</ul>

You would need to set the initial value of searchString to an empty string as well to match against all people when no text has been entered.

$scope.searchString = '';

Here is a Plunker demonstrating the functionality.

Hopefully that helps!
